Description:

PRIORITY

[0001] This application claims priority under 35 U.S.C. §119(a) of a
Korean Patent Application filed in the Korean Intellectual Property
Office on Aug. 2, 2010 and assigned Serial No. 10-2010-0074674, the
entire disclosure of which is hereby incorporated by reference.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a portable terminal. More
particularly, the present invention relates to a portable terminal for
having a detachable BLUETOOTH headset realized to make common use of a
receiver module and a microphone module in a case where the BLUETOOTH
headset is installed in the portable terminal.

[0004] 2. Description of the Related Art

[0005] Owing in large part to the development of various kinds of
electronic and telecommunication industries and technologies, portable
terminals are widely popular, and tend to be diversified in function so
as to meet users' needs and desires, while also becoming gradually
smaller with miniaturization of electronics.

[0006] Accordingly, peripheral devices that are attachable or added to the
terminals are also in development and use and, for example, may include a
built-in digital camera, a smart card that is also an auxiliary memory,
an ear microphone mounted on the terminal and installed to enable a phone
call, a detachable broadcast antenna for receiving a sky wave broadcast,
a BLUETOOTH headset for wirelessly communicating by means of a BLUETOOTH
module installed in the terminal, and the like.

[0007] The terminals having the BLUETOOTH function mount a separate
BLUETOOTH antenna module for operating at a 2.4 GHz band, apart from a
main communication antenna module. A predetermined BLUETOOTH antenna
module is mounted in a main board of the terminal and performs local area
wireless communication with the BLUETOOTH headset.

[0008] The BLUETOOTH headset is used as part of a handsfree use of a
portable terminal. Since the BLUETOOTH headset does not need a separate
cable with the terminal, the BLUETOOTH headset has an advantage not only
in that a convenience of terminal manipulation increases, but also in
that carrying is simple and convenient in comparison with a general
handsfree wired ear microphone. So, adoption of the BLUETOOTH headset has
gradually become more generalized.

[0009] On the other hand, products improving the portability of the
BLUETOOTH headset are recently entering the market. For example, in the
case of when the BLUETOOTH headset is not being used, the BLUETOOTH
headset is installed in the portable terminal and carried together with
the portable terminal, so a danger of forgetting or losing the BLUETOOTH
headset is less than when they are carried separately.

[0010] But, the above terminal detachable BLUETOOTH headset simply
concerns only a carrying convenience, and is difficult to find additional
efficiency. For instance, receiver and microphone modules for a portable
terminal and receiver and microphone modules for BLUETOOTH should be
provided individually, and this has resulted in a problem in that a
corresponding cost has been high until now.

stated otherwise. A set is defined as a non-empty set including at least
one element.

[0036] FIG. 1 is a rear perspective diagram illustrating a portable
terminal equipped with a BLUETOOTH headset according to a first exemplary
embodiment of the present invention. FIG. 2 is a rear perspective diagram
illustrating a portable terminal unequipped with a BLUETOOTH headset
according to the first exemplary embodiment of the present invention.
FIG. 3 is a front perspective diagram illustrating a portable terminal
equipped with a BLUETOOTH headset according to the first exemplary

[0037] Referring to FIGS. 1 to 3, a BLUETOOTH headset 10 according to the
first exemplary embodiment of the present invention is installed
detachably in a suitable place of a portable terminal 100. In the
drawings, the portable terminal 100 may have an installation part 103 of
a groove shape in a suitable place of the portable terminal's rear
surface 102, and the BLUETOOTH headset 10 may be installed detachably in
the installation part 103 of the portable terminal 100.

[0038] In this exemplary embodiment, the BLUETOOTH headset 10 is installed
in the rear surface 102 of the portable terminal 100. In detail, if a
battery cover (not shown) detachably installed in the whole rear is
uncovered, the installation part 103 may be exposed, and the BLUETOOTH
headset 10 may be installed detachably in the exposed installation part
103 of the portable terminal 100.

[0039] But, this does not limit the scope of the present invention, and
the BLUETOOTH headset 10 may be directly installed detachably in a rear
surface 102 of the portable terminal 100 without doing damage to an
appearance of the portable terminal 100.

[0040] In an exemplary embodiment of the present invention, a receiver
module (`R` in FIG. 5) and microphone module (`M` in FIG. 5) of the
BLUETOOTH headset 10 are used as a combined receiver module and
microphone module of the portable terminal 100. Thus, in a case where the
BLUETOOTH headset 10 is uninstalled from the portable terminal 100 and is
used as a handsfree device, the BLUETOOTH headset 10 is used as a general
BLUETOOTH headset. But, in a case where the BLUETOOTH headset 10 is
installed in the portable terminal 100, the BLUETOOTH headset 10 may not
function as the general BLUETOOTH headset but instead function as a
receiver module and microphone module of the portable terminal 100. So,
desirably, as illustrated in FIG. 3, the BLUETOOTH headset 10 may be
installed in a vicinity of a speaker hole 107 and a microphone hole 106
that are formed in a front surface 101 of the portable terminal 100. That
is, the receiver module and microphone module of the BLUETOOTH headset 10
may be installed such that they respectively correspond to the speaker
hole 107 and the microphone hole 106 of a case frame that is formed in
the front surface 101 of the portable terminal 100. More desirably, when
the microphone module of the BLUETOOTH headset 10 is used for the
portable terminal 100, the microphone module of the BLUETOOTH headset 10
may be used as a sub microphone module that may be used for audio
feedback prevention, speaker phone call, and echo cancelation function
realization.

[0041] FIGS. 4A and 4B are perspective diagrams illustrating an operation
state of a BLUETOOTH headset according to the first exemplary embodiment
of the present invention. FIG. 5 is a cross-sectional diagram
illustrating a key construction of a BLUETOOTH headset according to the
first exemplary embodiment of the present invention.

[0042] Referring to FIGS. 4A-4B and 5, the BLUETOOTH headset 10 includes a
body 11 shaped to correspond to the installation part 103 of the portable
terminal 100, an ear cap 13 having a receiver hole 131 and
protrusion-formed in the body 11, and a microphone hole 14 formed at a
suitable place of the body 11. The ear cap 13 may be installed to show up
from a hollow-type bushing 12 that is protrusion-formed in the body 11.
In FIG. 4A the ear cap 13 is shown in an extended state, and in FIG. 4B
the ear cap 13 is shown in a retracted state.

[0043] Desirably, as illustrated in FIG. 5, when the BLUETOOTH headset 10
is installed in the portable terminal 100, the ear cap 13 may move inside
the bushing 12 and, when the BLUETOOTH headset 10 is uninstalled from the
portable terminal 100, the ear cap 13 may automatically protrude as much
as a predetermined height by means of a predetermined elastic means. The
elastic means may be a compression type coil spring 16.

[0044] A receiver module (R) may be disposed within the body 11 at a
location corresponding to the receiver hole 131 of the ear cap 13, and a
microphone module (M) may be disposed within the body 11 at a location
corresponding to the microphone hole 14.

[0045] A terminal part 15 is constructed in the body 11 of the BLUETOOTH
headset 10. When the BLUETOOTH headset 10 is installed in the
installation part 103 of the portable terminal 100, the terminal part 15
of the BLUETOOTH headset 10 electrically connects with the portable
terminal 100 and allows the receiver module (R) and the microphone module
(M) to be used for the portable terminal 100. Thus, although not
illustrated, a protruded connector part of an exemplary embodiment of the
present invention may be formed in the installation part 103 of the
portable terminal 100 to contact the terminal part 15 of the BLUETOOTH
headset 10. But, this does not limit the scope of the present invention.
For example, if the connector part is formed in the BLUETOOTH headset 10,
the terminal part 15 may instead be formed within the installation part
103 of the portable terminal 100.

[0046] More desirably, the BLUETOOTH headset 10 uses a general receiver
module R used in the portable terminal 100. When the BLUETOOTH headset 10
is used as a BLUETOOTH headset, the receiver module R may reduce an
output. More desirably, if a controller of the portable terminal 100
senses through the terminal part 15 that the BLUETOOTH headset 10 is
detached from the portable terminal 100, the controller may perform an
operation of automatically entering a pairing mode. Also, in a case where
the controller of the BLUETOOTH headset 10 senses that the BLUETOOTH
headset 10 is detached from the portable terminal 100, the controller may
automatically reduce an output of the receiver module R and convert into
a BLUETOOTH mode.

[0047]FIG. 6 is a perspective diagram illustrating a construction of a
BLUETOOTH headset according to a second exemplary embodiment of the
present invention. FIG. 7 is a perspective diagram illustrating an
operation state when a portable terminal is equipped with a BLUETOOTH
headset according to the second exemplary embodiment of the present
invention.

[0048] The first exemplary embodiment of the present invention illustrates
and describes a bar-type BLUETOOTH headset 10, but this exemplary
embodiment illustrates a foldable BLUETOOTH headset 20. The foldable
BLUETOOTH headset 20 has an advantage of being capable of efficiently
using an installation space of the portable terminal 100. Also, although
not illustrated, there is also provided a terminal part similar to
terminal part 15 described above for electrically connecting the
BLUETOOTH headset 20 with the portable terminal 100 when the BLUETOOTH
headset 20 is installed in the portable terminal 100. Other mode
conversions upon installation/uninstallation and the like are
substantially the same as those of the first exemplary embodiment.

[0049] The foldable BLUETOOTH headset 20 includes a first body 21, and a
second body 22 installed to rotate with respect to the first body 21. As
illustrated in FIG. 7, the first body 21 and the second body 22 may be
mutually folded to face each other.

[0050] In the first body 21, a bushing 211 may be integrally formed to
house an ear cap 212 shown here in an up or extended state, and a
receiver hole 213 may be realized in the ear cap 212. In the second body
22, a microphone hole 221 is formed. A receiver module and a microphone
module may be disposed in the bodies 21 and 22, respectively. An
operation of extending and retracting the ear cap 212 may be realized in
the same manner as that of the ear cap 13 of the first exemplary
embodiment.

[0051] In an exemplary embodiment, a pair of side hinge arms 214 may be
formed in the first body 21, and a center hinge arm 222 may be formed in
the second body 22 to rotate interposed between the side hinge arms. But,
this does not limit the scope of the present invention, and various
schemes such as a foldable link, a multiple-joint structure, and the like
as well known in the art are applicable.

[0052]FIG. 8 is a perspective diagram illustrating a state where a
portable terminal is equipped with a BLUETOOTH headset according to the
second exemplary embodiment of the present invention.

[0053] Referring to FIG. 8, in a case where the BLUETOOTH headset 20 is
installed and used in a portable terminal 100, in the configuration of
FIG. 7, the first body 21 and the second body 22 are folded to be in a
more compact shape. In this state, if the BLUETOOTH headset 20 is
installed in the portable terminal 100, a receiver module of the
BLUETOOTH headset 20 may be used for a receiver module of the portable
terminal 100, and a microphone module of the BLUETOOTH headset 20 may be
used for a sub microphone module of the portable terminal 100.

[0054] In a case where the BLUETOOTH headset 20 is uninstalled from the
portable terminal 100 and is used for handsfree use of a privacy call and
the like, the first body 21 and the second body 22 may be arranged
unfolded and used in a straight line as in FIG. 6.

[0055] In the described exemplary embodiments of the present invention,
the BLUETOOTH headsets 10 and 20 are described by way of exemplary
embodiments of the bar type, the foldable type, and the like, but this
does not limit the scope of the present invention. For example, BLUETOOTH
headsets of various forms such as a show-up type BLUETOOTH headset in
which bodies are shown up in sequence, a type in which a first body
itself may be inserted into a user's ear, and the like may be applied
according to a mounting space of a portable terminal with which they are
to be used. But, all the aforementioned BLUETOOTH headsets make common
use of a receiver module and a microphone module for a portable terminal.

[0056] In the described exemplary embodiments of the present invention,
the BLUETOOTH headset 10 or 20 is installed in the rear surface of the
portable terminal 100, but this does not limit the scope of the present
invention. Also, various installation schemes may be applied according to
